This rock-cut Byzantine complex, 10km south of Mustafapaşa, is a labyrinth of a place with 16 houses where hundreds of monks lived. Inside the dwellings you can see fireplaces, bookshelves and grey nicks left on the rock by metal chisels. The kitchen features a hatch for passing meals to the refectory , which has seats at the far end for the teachers. The Stephanos Church here has a very well-preserved cross-form ceiling fresco that extends all along the vault.
